Systematic Approach on Modeling and Identification for Nanobattery Prototyping

This article is concerned with the systematic design of nanobattery prototyping. Miniaturization of power sources is a challenging area of nanotechnology research. There are four major parts in miniaturized Li-Ion nanobattery: anode, cathode, electrode and separator. Correspondingly, some appropriate material must be distinguished. The multiwalled carbon nanotube array electrode is used as anode, which exhibits high current density. LiMn₂O₄ spinel oxide is used as the cathode. Nanoporous dielectric membrane is selected for mixture storage of gel electrolyte. Ni is chosen as a suitable current collector. The separator and electrolyte container accounts for the reduction of dendrites and compatibility increment of electrode-electrolyte. According to nanobattery physical mechanism, mathematical model has been identified. At last, some numerical simulations of nanobattery characteristics have been conducted.
